This is a no-nonsense, easy-to-use book that is an ideal size for carrying along on outdoor activities. Contains over 730 native (and important introduced foreign) tree species that might be found on a wilderness hike. It is very nicely presented with numerous leaf samples on each page for ease of comparison. Some entries contain flowers, bark, fruit, winter silhouette or landscape shape and size to help with identification. Brockman also includes a guide to tree families so that the relationships can be understood better.
